●

Description

These clock generators are an IC generating three types of clocks - VIDEO, AUIDIO and SYSTEM clocks – necessary for

DVD player systems, with a single chip through making use of the PLL technology. Particularly, the VIDEO clock is a

DVD-Audio reference and yet achieves high C/N characteristics necessary to provide high definition images.

●

Features

1) Connecting a crystal oscillator generates multiple clock signals with a built-in PLL.

2) The AUDIO clock provides switching selection outputs

3) The VIDEO clock achieves high C/N characteristics.

4) Single power supply of 3.3 V
